The portable asphalt coating equipment, as a new method of asphalt coating for the reduction of negative friction acting to piles, has been developed. The asphalt sheet, cooled and shaped by the rotary cooling drums, is winded to the steel tube, while the asphalt has the plasticity in a certain range of temperature. The characteristic feature of this equipment is as follows : (1) The equipment is compact and able to coat asphalt easily at the site where piles are drived. Thus the problems encountered on the transportation or the storage, i.e. damages of coating, can be settled. (2) The coating thickness is uniform over the whole length of piles, as a result of coating method of sheet winding. Also, coating adhesion is excellent. By the actual piling test, the coated piles produced by the new method were confirmed to be able to put to practical use.
